The Allen-Bradley PTCD Push Button Contact Block Assembly is a micro switch‑based contact block (model PTCD) that complements push‑button devices to provide a discrete electrical contact when actuated. This assembly serves as the switching element in industrial control circuits, translating a button actuation into a signal for the controller. Use of this PTCD contact block is typical in panels that require reliable mechanical-to-electrical signaling from push-button inputs.
